Armando Iannucci's biting political satire is back to poke fun mercilessly at the coalition, spin doctors and the most bonkers elements of British politics.
With f-bombs and quotable one-liners at every turn ("I hate school children, they are volatile, stupid and they don't have the vote. I may as well be talking to f**king geese"), the show has lost none of its spark heading into its fourth run.
Watch a one-minute teaser clip of the first episode below:
The big question is what has happened to Peter Capaldi's devilish Malcolm Tucker following the government shake-up? Is it possible for him to get even angrier and more foul-mouthed now that he's on the sidelines?
The Thick of It returns on Saturday (September 8) at 9.45pm on BBC Two.
